At this stage, the flame is about one,four hundred °C (2,550 °File). Having said that, this Portion of the flame is rather small and releases minimal warmth Vitality. The blue shade is due to chemiluminescence, although the seen yellow color is due to radiative emission from incredibly hot soot particles.
